The two crushed up a bit of the client’s medicinal weed into tiny pieces. Then Pham encapsulated the leaves in gel polish on every other nail.

She painted the other nails black and green with dripping gold glitter to resemble cannabis oil.

The manicure was a big hit at the convention, said Pham.

“People were stopping by her booth at Hemp Con just looking at her nails,” she said.

But Pham’s client is not alone. The “weed nail” trend has flourished over the last couple of years as states begin to legalize recreational and medicinal marijuana, bringing potheads out of the shadows and apparently into nail shops.

But before you grab a pinch of bud and head to your local nail shop, remember that weed is still not totally legal to possess in all states.

“While it would probably be rare and ridiculous, it is possible that someone with marijuana stuck to their nails could be arrested or cited for possession by an overzealous police officer if marijuana is not legal in their state,” said Morgan Fox, a spokesperson for Marijuana Policy Project, in a statement to BuzzFeed News.

Fox suggests people interested in getting a weed manicure review their respective state laws and policies.

He adds that anyone who is interested in providing weed manicures should consult an attorney who specializes in this area for advice.

While pot nail art may seem bizarre, Pham said she has done “crazier things” like creating 3-D art on nails or gluing seashells and real flowers to them.
